Summary

The purpose of this study is to compare the effect of ingesting caffeine and mixed flavonoids (4 capsules, split between breakfast and lunch) on energy expenditure and fat oxidation in a metabolic chamber with 20 women (non-obese, healthy, ages 20-47 years, pre-menopausal). We hypothesize that based on the existing literature, ingestion of a double dose of the caffeine-mixed flavonoid supplement compared to placebo will increase fat oxidation and increase 24 h energy expenditure by about 75 kilocalories.
